(a)
Interpretation: To determine the step of the urea cycle in which ATP is consumed.
Concept introduction: Urea cycle is a cyclic biochemical pathway that involves the production of urea using ammonium ions and aspartate molecules as nitrogen sources. It converts toxic ammonium ion to urea which is then excreted from the body in urine. The urea cycle is as follows:
Adenosine triphosphate (ATP) is a molecule that is defined as the energy currency of life and provides energy to carry out the
(b)
Interpretation: To determine the step of the urea cycle in which ATP is produced.
Concept introduction: Urea cycle is a cyclic biochemical pathway that involves the production of urea using ammonium ions and aspartate molecules as nitrogen sources. It converts toxic ammonium ion to urea which is then excreted from the body in urine.
The urea cycle is as follows:
Adenosine triphosphate (ATP) is a molecule that is defined as the energy currency of life and provides energy to carry out the metabolic processes in the living cells. It is converted either to adenosine monophosphate (AMP) or to adenosine diphosphate (ADP) after the consumption in the metabolic processes.
